Polymer banknotes saw the end of the watermark, which was replaced with

Serial Numbers

Introduction of the Two letter & Two number Prefix
AB10 – AB33

Notes :
This note was the first circulation issue Australian polymer banknote. The first printing had
a thin, smooth varnish over the hologram which rapidly rubbed off when used. Printing was stopped
when the problem was identified.

All first printing [general circulation] notes have a serial
number prefix between AB10 and AB 33
with the first two digits of the number being 93, 94 or 96 [AB 33 965070].

An Elaborate Field Test
Much was riding on the $10 note circulating in a satisfactory manner  over $20 million had been
sunk into research and production costs in this technology over two decades, with the intention that Australia
would eventually convert it's entire circulating currency to the new "plastic fantastic" notes,
after which the technology would then be exported the world over.
No less than 11 distinct varieties have been identified, the rarest of them has a catalogue value of
$38,000.
